I'm 27 and have had moderate acne since I was a teenager. Tried so many things, nothing seems to work so I kind of gave up. But my acne got significantly better last year, during which time I was taking a few aspirin a day for another condition. I thought it had mostly cleared and my hormonal issues had just resolved or something, but since I stopped taking aspirin (2-6 pills/day) regularly it's come back. I'm thinking I should start taking aspirin again!

I think it makes sense that aspirin would help because its an anti-inflammatory. Eating yogurt regularly also seemed to help.
